Tonight for instance reports a temporary service outage (3 times, around 15′ each) caused by an intermittent unavailability of the GitHub API. As GitHub was not able to provide the validity of its OAuth code credentials, GerritHub was not able to allow the completion of its login handshake and thus resulting in a partial outage.

We will use the PingDom.com reports to reinforce our production infrastructure and make GerritHub.io more resilient in the future. For instance in this case (GitHub API unavailable) we will look at reusing cached credentials for allowing known people with non-expired Gerrit cookies to complete their operations. For unknown users, we will display next time a courtesy message explaining that the sign-up is unavailable for GitHub API temporary outage, avoiding the allocations and time-outs of HTTP connections.
